Well people seem to be forgetting that the summary of the episode says that twilight cast a spell that switches everyone's cutie marks and destinies. I think what is likely to happen is that in casting that spell, Twilight accidentally created an alternate reality where she is a princess and so when she fixes everyone's cutie marks, she will also so back to normal. But as I said before, only time will tell if I'm right.
